`@Published` properties that views subscribe to for UI updates need to
be updated from the main thread only. This PR annotates the relevant
variable and function from the original author's implementation with
`@MainActor` so that Swift will properly warn us when modifying these in
the future.
A regression was introduced in #8218 that removed the `menuBar` as an
environment object for `AppView`.
Unfortunately this compiles just fine, as EnvironmentObjects are loaded
at runtime, causing the "Open Menu" button to crash since it's looking
for a non-existent EnvironmentObject.
This configures the GUI client to log to journald in addition to files
as well. For better or worse, this logs all events such that structured
information is preserved, e.g. all additional fields next to the message
are also saved as fields in the journal. By default, when viewing the
logs via `journalctl`, those fields are not displayed. This makes the
default output of `journalctl` for the FIrezone GUI not as useful as it
could be. Fixing that is left to a later stage.

With the addition of the Firezone Control Protocol, we are now issuing a
lot more DNS queries on the Gateway. Specifically, every DNS query for a
DNS resource name always triggers a DNS query on the Gateway. This
ensures that changes to DNS entries for resources are picked up without
having to build any sort of "stale detection" in the Gateway itself. As
a result though, a Gateway has to issue a lot of DNS queries to upstream
resolvers which in 99% or more cases will return the same result.
To reduce the load on these upstream, we cache successful results of DNS
queries for 5 minutes.

On Linux, logs sent to stdout from a systemd-service are automatically
captured by `journald`. This is where most admins expect logs to be and
frankly, doing any kind of debugging of Firezone is much easier if you
can do `journalctl -efu firezone-client-ipc.service` in a terminal and
check what the IPC service is doing.
On Windows, stdout from a service is (unfortunately) ignored.
To achieve this and also allow dynamically changing the log-filter, I
had to introduce a (long-overdue) abstraction over tracing's "reload"
layer that allows us to combine multiple reload-handles into one.
Unfortunately, neither the `reload::Layer` nor the `reload::Handle`
implement `Clone`, which makes this unnecessarily difficult.

Now that we have error reporting via Sentry in Swift-land as well, we
can handle errors in the FFI layer more gracefully and return them to
Swift.

The `wintun` crate will already shutdown the session for us when the
last instance of `Session` gets dropped. Shutting down the session prior
to that already results in an attempt to close an adapter that is no
longer present, causing WinTUN to log (unactionable) errors.
Alternative to #8128. If the user dismissed the unlock prompt or has
their keyring otherwise misconfigured, it is still useful to allow them
to sign-in. They just won't stay signed-in across reboots of the device.
When we receive an inbound packet from the TUN device on the Gateway, we
make a lookup in the NAT table to see if it needs to be translated back
to a DNS proxy IP.
At present, non-existence of such a NAT entry results in the packet
being sent entirely unmodified because that is what needs to happen for
CIDR resources. Whilst that is important, the same code path is
currently being executed for DNS resources whose NAT session expired!
Those packets should be dropped instead which is what we do with this
PR.
To differentiate between not having a NAT session at all or whether a
previous one existed but is expired now, we keep around all previous
"outside" tuples of NAT sessions around. Those are only very small in
their memory-footprint. The entire NAT table is scoped to a connection
to the given peer and will thus eventually freed once the peer
disconnects. This allows us to reliably and cheaply detect, whether a
packet is using an expired NAT session. This check must be cheap because
all traffic of CIDR resources and the Internet resource needs to perform
this check such that we know that they don't have to be translated.
This might be the source of some of the "Source not allowed" errors we
have been seeing in client logs.
We appear to have caused a pretty big performance regression (~40%) in
037a2e64b6 (identified through
`git-bisect`). Specifically, the regression appears to have been caused
by [`aef411a`
(#7605)](aef411abf5).
Weirdly enough, undoing just that on top of `main` doesn't fix the
regression.
My hypothesis is that using the same file descriptor for read AND write
interests on the same runtime causes issues because those interests are
occasionally cleared (i.e. on false-positive wake-ups).
In this PR, we spawn a dedicated thread each for the sending and
receiving operations of the TUN device. On unix-based systems, a TUN
device is just a file descriptor and can therefore simply be copied and
read & written to from different threads. Most importantly, we only
construct the `AsyncFd` _within_ the newly spawned thread and runtime
because constructing an `AsyncFd` implicitly registers with the runtime
active on the current thread.
As a nice benefit, this allows us to get rid of a `future::select`.
Those are always kind of nasty because they cancel the future that
wasn't ready. My original intuition was that we drop packets due to
cancelled futures there but that could not be confirmed in experiments.
Notifications on Apple platforms are delivered with best-effort
reliability and are not guaranteed.
They can also be queued up by the system so that, for example, it's
possible to issue a notification, quit the app, and then upon the next
launch of the app, receive the notification.
In this second case, if the user dismissed the notification, we will
crash. This is because we only track the `lastNotifiedVersion` in the
`NotificationAdapter` instance object and don't persist it to disk, then
we assert the value not to be nil when saving the user's `dismiss`
action.
To fix this, we persist the `lastNotifiedVersion` to the `UserDefaults`
store and attempt to read this when the user is dismissing the
notification. If we can't read it for some reason, we still dismiss the
notification but won't prevent showing it again on the next update
check.
A minor bug is also fixed where the original author didn't correctly
call the function's `completionHandler`. Also, unused instance vars
`lastDismissedVersion` left over from the original author are removed as
well.
With the dependency bump in #7995, we introduced a visual regression
that made all windows lose their styling:
The changelog to the v4 bump actually mentions some breaking changes and
an automated upgrade tool but both the reviewer and the author of the PR
missed that.
We currently have a bug in our changelog where the wrong download links
are being rendered for the Windows GUI client because we are incorrectly
matching on the title.
To fix this, we stop matching on the title and instead pass an `OS` enum
in the respective changelog components that need to differentiate
between OS-specific entries.
Whenever changing a URL we care about, we add an entry in
`website/redirects.js` to avoid breaking links to the old page. Most
search engines reindex these after 1 year, but other websites and places
won't, so we should generally keep them indefinitely since they don't
cost us much to keep around.
When the IPC service gets terminated gracefully, the user must have
initiated some kind of action, be it an upgrade or an explicit "Stop the
service". In that case, there is no point in displaying an alert with an
info / error message as the user already knows that they are stopping
Firezone. In order to not fatigue the user with alerts, we exit the GUI
with a toast notification when the IPC service shuts down gracefully.
Toast notifications do not grab the users attention, allowing them to
continue what they are doing while still being notified that their
Firezone client is now disconnected.
Fixes: #6232.
This adds the following for the headless Windows client:
- website download redirects to use for permalinks
- Windows headless client user guide
It also cleans up old references and a few minor related things I found
while working on this.

This updates `wintun` to include
https://github.com/nulldotblack/wintun/pull/27. The error message of the
linked Sentry issues in #7901 of "Unable to find matching {UUID}" is
removed in that PR in favor of a Win32 function that converts the
adapter name directly to the corresponding index and UUID instead of
searching through the list of adapters.
Resolves: #7901.
